Novel knitted fabric

ABSTRACT

A novel knitted fabric includes a double-sided structure which is weft-knitted by a natural fiber or a viscose, a sorona and a polyurethane fiber. A first side of the double-sided structure is constituted by the natural fiber or the viscose and the polyurethane fiber, a second side of the double-sided structure is constituted by the sorona, and a yarn ingredient proportion comprises 60-50% of the natural fiber or the viscose, 40-30% of the sorona, and 5-20% of polyurethane fiber. The novel knitted fabric can have advantages of excellent stretchability, recoverability, plastic and packaging functions, wearing comfort, and conformation of modern environmental thoughts.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a textile manufacturing field, inparticular relates to a novel knitted fabric.

2. Description of the Related Art

Traditionally, sportswear is majorly fabricated by polyethyleneterephthalate and nylon. Polyethylene terephthalate and nylon arepetroleum products and most dependently obtained therefrom, but theseproducts surely cause lots of pollutions to our environment. Purenatural cotton fiber is characterized with excellent moistureabsorption, moisture retention and skin-friendly effects, but defectssuch as inferior elasticity, extensibility and strength, tendency totension fracture, and less wear resistance are relatively existed,incapable of satisfying requirements of sport fabrics. Fabrics made ofnatural fiber or a viscose mixed with polyurethane fiber can haveexcellent wearing comfort, but they still have defects of less strengthand bursting effect, inferior tension fracture, and tendency towrinkling and deformation are existed. Fabrics made of nylon,polyethylene terephthalate and polyurethane fiber can have excellentstrength, and difficulties of being burst and torn, but they still haveless skin-friendly effect and cause serious pollutions to ourenvironment. In America, Du-Pont Company disclosed a sorona polymerwhich contains a raw material of 37% obtained from nonpetroleumregenerative sources, capable of greatly reducing the human dependencyof acquiring materials from limited petroleum sources and thereforeobtaining reductions of a source consumption of 30% and a carbon dioxidegas discharge of 63% so that a perfect combination of functionalities ofthe related textile productions and purpose of environmental protectionscan be attained. Besides, sorona fiber is characterized with excellentstretchability and recoverability and properties of chloride resistance,ultraviolet resistance and anti-pollution and easy-to-clean effects,thus to be extensively applied on different kinds of clothing fabrics.However, fabrics made by adding sorona into the natural fiber or theviscose only can provide a slight flexibility, i.e., without highflexibility and high recoverability, and imperfect plastic effects. Toovercome the above difficulties, technicians in this field shall studyand develop how to apply an environmentally-protective fiber materialsto allow a knitted fabric for preserving excellent functions oftraditional chemical fiber fabrics and how to particularly provideadvantages of skin-friendly effects, comforts, natures and environmentalprotections, which are also the production of the invention accordingly.
